Ardie,
Fat Agnus is simply the square chip agnus. You've already got
that, I presume you mean "Super Agnus"…and no…it has no memory on it's
own, it just allows the other custom chips to access a full Meg of RAM
rather than just 512K..so essentially, it's just remapping memory.
Yes, modifications must be made. A jumper needs to be switched (no
big deal there) and a very small trace…in a very crowded (trace wise)
area needs to be cut (that is a big deal if you cut one of hte other
traces!).
